i yuy- 'will t glielo Specification o'etters Patent 'i ...amata Application filed July it, L91 l. Serial No, 648,635.

To all whom t may concern Be it known that l, Hnncnnr CHAuLns RICH, subject of the King of Great Britain, residing at 1ST New North road, Horton, London,blnglanddiave invented certain new and useful lmprovoinents in and Relating to Spraying Apparatus, oli which the follow* ing is a specification.

This invention for improvements in and relating to spraying apparatus has for its object to provide an efficient spray for paint and other solutions and consists substantially of a cylindrical reservoir or container having an opening at one end and a nozzle arranged therein and-an air tube adapted to supply air under pressure to the nozzle which is carried on said airtube. The air tube which passes axially through the reservoir is adj ustably connected thereto in such a manner that the nozzle can be caused to advance toward or to recede from the opening at the end et the reservoir in order to vary the amount of solution sprayed.

ln one way of carrying out this invention the spraying apparatus comprises two tubes having a sliding connection and adapted to be secured by a bayonet catch, thus forming a reservoirn and a-centrally arranged air tube which screwed 'through the rear end of the reservoir. The forward end of the reservoir is :termed with an opening` into which projects the nozzle providedv on the end of the aiixtube, The air tube is supported centrally within the reservoir by a suitable guide collar and by the screw connection between said air tube and reservoir. The air nozzle can be moved toward or away from the opening in the end of the reservoir as desired.

The air tube extends rearwardly beyond the end or' the reservoir and is preferably provided with a union connection 'for a flexible air pipe. It valve may be provided in the air tube outside the reservoir for the purpose of regulating the air supply.

ln the accompanying' sheet of drawings: Figure l is an elevation of the spraying apparatus. Fig. 2 a longitudinal section of the saine and Fig', 3 is a transverse section through 3--3 in Fig'.

As seen in Figs. l and 2 the spraying ap paratus comprises an air tube a. Which isl .sui table surrounded by a liquid. reservoir. tibo reservoir consists of two tubes l) and one of which3 Zr, ts Within the other, at and il; secured thereto by a, bayonet fastening (L The end of the tube c is closed by a cap c which is screwed on the air tube a, being fixed by a lock nut e', While the end of the tube Z2 has anozzle f With a central opening?,n f, the nozzle y serving also as cap. The air tube a is supported centrally Within the riser-voir by a collar' g having three arms which bear against the inner surface of theA tube while at its end a point-ed nozzle e is provided which projects into the central opening j" of the nozzle or cap f. The position of the nozzle it Within' the openingn f. can be adjusted as desired in order to vary the amount of liquid to be sprayed by rotating the reservoir around the air tube a. At its rear end the air tube o is provided with a. connection z' for a liezible pipe which isaltaclied to the air tube by a union j. In order to open the reservoir it is screwed diorn Ward on the air tube and the art o is 'then rotated on the 'part c and with ravn. When )char-eed and reassembled the air tube is forward int-e the reservoir until e space is left between the nozzle fz, and the openingv in the cap j". The tube a is new connected to a compressed air supply pipe suitably controlled by a valve (not shown), and the spraying apparatus is now Y ready for use.

The apparatus when in use is turned downward and the rush of air through the nozzle ,7L causes'the solution to spray out et the cap j' by the suction produced.

Having thus described my invention, what' l claim and desire to secure by Letters Patent is A spraying' apparatus comprising in eombination, two telescopic cylindrical sections adapted toriiorni aY liquid reservoir, a baycnet slot connection between said telescopic sections, a closure for one end of said reser- Voir having a threaded aperture therescrewed through, and a nozzle closure for the other end ot' said reservoir, an air tube entering the threaded aperture in said lirst inentioned closure, a nozzle disposed on the end ot said air tube and having its opening concentric and .lyingr Within the opening of said lili til!
